Application filed December To all whom it may com-em:

Be it known that I, Cmnnnon Ross BRY- ANT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Wrenches, of which the following is a specification.

This invention relates to wrenches of the spanner type and an object of the invention is to provide a wrench which is particularly adapted for the turni of nuts in close places, the nut turning cans of the wrench bein arranged to permit a relatively large num of nut engaging positions of the wrench thereby permitting the turning of the wrench in a relatively small place.

' More specifically the invention comprehends the provision of a wrench which has nut turning means of uniform size on each end of its handle, the angled faces of the nut turning means on one end of said handle being disposed at an angle to the faces of the nut turning means on the opposite end of the handle equal to substantially one-half of the degree of the angle of the faces of each nut engaging means one to the other.

Another object of this invention is to provide a wrench as specified which is adapted for oo-op eration with sockets of various sizes for engagement with nuts'of various sizes, the said sockets being provided with uniform portion for engagement by the wrench proper, thereby permitting the use of a single wrench with a plurality of sockets of different sizes a1 owing the wrench to be packed in a relatively small space for carryi about.

Other objects 0 the invention will appear in the following detailed description and in the accompanying drawings wherein:

Fig. 1 is a plan of the improved wrench.

Fig. 2 is a side elevation of the wrench,

Fig. 3 is a section through a socket emlployed with the wrench.

employed with the modified form of the wrench. r

Fig. 10 is a' plan of modified form of socket. A

Fig. 11 is a section through the modified form of the socket.

Fig. 12 is a fragmentary plan of the wrench showing one of its nut turning ends in engagement with the socket.

Fig. 13 is a fragmentary. plan of the wrench showing the nut turning end opposite from that shown in Fig. 12 mounted upon the socket and cooperating with the ig. 12 in illustrating the relative positions of the connecting handle of the wrench when .the nut turning means at its 0 posite ends are in operative engagement with a nut or nut turning socket.

Referring more particularly to the draw ing, the improved wrench comprises a connecting handle 1' which has nut turning heads 2 and 3 formed upon its opposite ends and in the preferred form of the invention these nut turning heads 2 and 3 comprise polygonal lateral projections on the handle 1. The number of sides. of the polyhedral heads 2 and 3 may be varied, depending upon the type of nuts or sockets to be turned, that is they'may be rectangular, octagonal, hexagonal or any of the other well known polygonal forms employed in the manufacturin of nuts. In'use, the polygonal nut turning heads 2 and 3 cooperate with sockets 4 one of which is illustrated in Figs. 3, 4 and 5 of the drawings. The sockets 4 have their inner surfaces 5 shaped to conform to the shape of the nut turning heads 2 and 3 irrespective of size of the nut engaging portion of the socket 4, the wrench head receivin portions are all uniform, i. e. in the manuf cture of the wrenches a pluralit of sockets 4 of various sizes may be provlded, the sizes of their wrench engaging portions varying in size to fit various sized nuts while all the other wrench head receiving ends are uniform or of the same size to receive the heads 2 or 3 to permit turning of the sockets and nuts engaged thereby, by the wrench structure. As clearly shown in Fig. 1 of the drawing the angled faces or sides of one of the heads are disposed at an angle to the angular faces of the other head, equal to substantially one-half of the degree of the angle of the facesof each of the heads thus permitting a relatively large number of adjustments of the position of the wrench to permit turning of a nut in a small space; for example, when the heads 2 and 3 are hexagon the relative positioning of the angled faces of one with the other will permit 12 distinct positions of the wrench relative to the nut being turned.

The modified form of wrench illustrated in Figs. 7 to 13 inclusive is also of the spanner type comprising the connecting handle 10 having heads 11 and 12 upon its ends which heads are substantially cylindrical in shape and are provided with polygonal shaped openings 13, the number of sides of each are regulated by the type of nut to he turned. v

In use the heads 11 and 12 are adapted to engage over the polygonal portions 14 of nut turning sockets 15 which sockets are provided with polygonal recesses 16 for engagement with nuts to be turned and in practice a number of sockets 15 will be provided which have various sized nut engaging polygonal recesses 16 but in which all of the polygonal wrench engaged portions 14 are of the same size to permit. the use of the wrench with a plurality of sockets.

As clearly shown in Figs. 7, 12 and 13 of the drawing, the angled faces of the recesses or openings 13 in the head 11 are disposed, at an angle to the corresponding angled' faces of the recesses or openings 13 in the head 12, which angle is equal to, substantially, one-half of the degree of the angle of the faces of the recesses 13 in the head 11 one to the other so that when the head 11 is in engagement with a poly onal portion 14 of the socket 15 the connecting handle 10 will be positioned at an angle to its position when the head 12 is in engagement with the polygonal portion 14 and thus a relatively large number of adjusted positions of the wrench may be had for turning a nut in a small space.

It is, of course, to be understood that the invention may be constructed in various other manners and the parts associated in different relations and, therefore, I do not desire to be limited in any manner except as set forth in the claim hereunto appended.

Having thus described my invention what I claim is:

A wrench comprising a handle, a solid polygonal turning head on each end of said handle,the head on one end of the handle projecting'in the opposite direction from the handle from the head upon the other end, the angular faces of the head at one end of the handle being disposed at an angle to the angle of the faces of the other head equal to substantially one half of the degree of the angle of the faces on each head one to the other.

In testimony whereof I aflix m signature.
